A spiral guiding drain structure is disposed on a toilet and includes a hidden segment and an open segment connecting with the hidden segment. The hidden segment passes through the toilet and has an inlet end leaving away from the open segment. The open segment is defined on an inner wall of the toilet and spirally surrounds the inner wall downward, a length of the open segment is at least ¾ circumference of the inner wall of the toilet, and the toilet includes a fence portion extending outwardly from a bottom rim of the open segment adjacent to an opening, and a height of the fence portion changes when an extending distance of the open segment from the hidden segment increases so that water flows out of the open segment, thus flushing the inner wall of the toilet.
